The forbidden energy gap of silicon is 1.1 eV and same for germanium is 0.7 eV. As the forbidden energy gap is quite moderate, an electron in valence band requires a small energy to cross the forbidden energy gap to become free. Even at room temperature, there are numbers of free ...
- Hint: The region at which electrons are not occupying is known as energy band gap or forbidden band. Silicon and germanium are semiconductors. Complete step-by-step solution- Bandgap is the energy difference between the bottom of the conduction band and top of the valence band...

My most frequent and effective way is the fabled ‘stress-sleep’. When I reach a tipping point of stress especially as a result of conflict I’ll simply go into hibernation冬眠;过冬. Usually for about 4 hours or so of deep sleep.Supposedly this is a leftover relic of my childhood ...
The timing is pretty great. I fell into the gap where unemployment had not been extended, so I only qualified for 6 months of benefits. I’ve been out of work since August, so my benefits will end very soon. With the new year, my COBRA payments have increased from $744 a month to...
C. It is nice of you to say so, but I'm busy tonight. -Wow! This is a marvelous room! You must spend a lot of time and energy in it. -___. A. Thanks you. It really cost me that much. B. Great, I am very art-conscious. C. Don't mention it. Liu...
In this technique, thermal energy is used to convert an electron in a triplet excited state to a singlet excited state, where it then emits in a fluorescence event. This process is called reverse intersystem crossing (rISC) and cancels all spin-forbidden processes [8]. Complete conversion of...
